To all whom it 11mg concern..-

Be it known that I, ANGELO MARUBIO, a

citizen of theUnited States, residing in Chicago, in the county of Cook and State of Illinois, have invented'a new and useful Im ance of a plumber, even where all that is required is simply to repacka valve. Sometimes to avoid this great annoyance and inconvenience the pipe leading to each faucet or cock is provided with its own separate shut-oif valve, but this adds very materially tothe original plumbing bill or cost of construction, and evenwhere such separate shutofi valves are provided they frequently become stuck or corroded fast from infrequent use, so that they cannot be turned without wrenching the lead pipe from its fastenings or injuring it.

The object of my invention is to provide an efficient and durable construction of cock or faucet by which the difficulties and objections heretofore experienced may be overcome and which will itselfloperate to automatically close the waterpipe to which the cock or faucet is attached by the mere act of unscrewing or removingit from said pipe and which at the same time will be of a simple and cheap construction, so that no material addition will be made to the cost of manufacture.

A further object is to so construct my inventionas to enable it to be readily applied to cocks or faucets already in use.

My invention consists in themeans I employ to accomplish these results-that is to say, it consists, in connection with a'cock or faucet of any ordinary or suitable construction and having a removable shell screwthreaded to the hollow stem or base-piece that connects with the water-pipe, of a suppleis caused or permitted to seat itself and close the pipe by the act of unscrewing or removing the portion of the cook or faucet carrying the main valve, and which supplemental valve is prevented from so seating itself and closing the pipe by an extension or projection on or engaged by the removable portion of the cook or faucet or some part thereof when the same is screwed home or inplace. For convenience I provide the cock or faucet with a supplemental hollow stem or thimble, in which I form the seat for the supplemental valve or ball, the supplemental hollow stem or thimble beingscrew-threaded to the ordinary or customary hollow stem or base-piece of the cook or faucet and the shell of the cook or faucet screw-threaded to the supplemental hollow stem or thimble. The extension or projection which engages the ball or supplemental valve to hold it normally open or unseated may be connected to any suitable part of the removable portion of the cook or faucet; but I prefer to connect it to the valve or valve-stem instead of directly to the removable screw-threaded shell.

In the accompanying drawings, forming a part of this specification, I have for convenience illustrated my invention asapplied to an ordinary faucet of the well-known Fuller type; but it will be understood by those skilled in the art that it may be readily applied to faucets and cooks of all different kinds of constructions. j,

111 the drawings, Figure 1 is a central longitudinal section, and Fig. 2 is a cross-section pipe and which-is provided with the customary screw-thread b on its end for connection with the shell of the cock or faucet. O is the removable shell of the cook or faucet, having E is the supplemental valve, the same be- 2 esaeu in g preferably a ball-valve, It is located back of the main valve D and removable shell 0 and operates to close the water-pipe when the shell 0 and the main valve D, carried by it, are removed, but not when said shell and valve are in place. I

F is the supplemental hollow stem or thimble, having internal screw-threads f for connection with the valve-shell C and external screw-threads f at its shouldered end for connection with the hollow stem or base-piece B of the cock or faucet. The valve-seat f for the supplementalvalve is preferably formed in the supplemental hollow stem or thimble F.

G is the extension or projection on or engaged by the removable portion of the cook or faucet and which by its engagement with the supplemental valve E causes the same to -remain normally unseated, thus leaving the water free to flow through the cook or faucet when the removable shell 0 is screwed home or in place. For convenience this extension or projection is preferably connected to the stem'd of the main valve, to which it is or maybe screwthreaded. To prevent the supplemental or automatic check-valve E from.

closing the pipe A by atmospheric pressure or suction when the water-supply is shut off at the shut-off valve in the main water-supplying pipe and the pipe A is being drained to prevent freezing I provide the hollow stem or base-piece B-witn one or more internal ribs or projections or other device b as, for example, a piece of wire-for preventing the ball E from fitting water-tight in said hollow stem or base-piece.

As in my invention the shell 0, valve D, and hollow stem or base-piece B may be combined with the supplemental valve E and.

supplemental thimble F and extension or projection G without requiring any change in the construction of said parts B C D, it will be seen that my invention may be readily and cheaply applied to cocks or faucets already in use by simply adding said parts E F G and the piece of wire 12, all of which are so simple in form that they may be furnished at very slight cost.

The operation of myinvention is as follows: \Vhen it is desired to repack or repair the main valve of the cook or faucet, all that is required issimply to unscrew the shell 0 and remove it, the mere act of unscrewing and removing it permitting the valve or ball E to seat itself and close the pipe automatically byth'e water-pressure, as the extension or projection G no longer holds said valve E unseated or open, and when the shell 0 is again screwed in place this causes theextension'or projection G to again unseat or open the supplemental valve E and hold it normally in this position, so that the cock or faucet-now again operates in the usual way.

In Fig. 1 the rib or projection b is shown in full lines as being made integral with the base-piece B- and in dotted lines as being made in a separate piece from the base or stem B--as, for example, of a piece of bent .wlre.

Where my'invention is to be appliedtoold cocks or faucets'already in use, I prefer to employ the separate piece or removable rib b, as shown in the dotted lines; but where my invention is used in cocks or faucets spe- ,cially manufactured for embodying it I refer to employ the integral construction 0 rib b and shown in the full lines in said flguh 1. In a cock orfaucet,the combination wlth the hollow imperforate base-piece B, of valveshell 0, valve D, supplemental valve E, supplemental screw-threaded thimble F, and removable extension or projection G, substantially as specified.

2. In acock or faucet, the combination with the hollow imperforate base-piece B, of valveshell 0, valve D, supplemental valve E, supplemental screw-threaded thimble F, extension or projection G, and a device I) in said base-piece B to prevent valve E fitting watertight therein, substantially as specified.

In a cook or faucet, the combination with the removable screw-threaded valve-shell havinga valve-seat, and a reciprocating main valve and valve-stem, of animperforatc stem or base-piece, a supplemental hollow stem or thimble screw-threaded thereto and to said valve-shell and provided with a valve-seat at its end connecting with said base-piece, and a supplemental valve in said basc-piecctheld normally open or unseated and automatically seating itself when the removable shell and main valve are removed, substantially as specified.

t. In a cockpr faucet, the combination with the removablescrewthreaded valve-shell having a valve-seat, and a reciprocating main Valve and valvc-stem,of an imperforatc hollow stem or basepiece, a supplemental hollow stem or thimble having internal screw-threads at one end connecting it with said valve-shell, said supplemental hollow stem or thimble havi-ngits opposite end shouldered and furnished with external screwthreads connecting it with said base-piece and provided at said end with a valve-seat, a supplemental valve in said base-piece held normally open or unseated and automatically seating itselfwhen the removable shell andmain valve are removed, and an extension or projection for holding said supplemental valve normally open orunseated when the main valve and shell are in place, substantially as specified.

5. In a cock or faucet, the combination with the base-piece B,,of valve-shell C, valve D, supplemental valve E, supplemental screwthreaded thimble F, and extension or projection G screw-threaded to the stem of the main valve, substantially as specified.

ANGELO MARUBIO.
